We get it -- your holiday guests are sleeping downstairs, you've still got last-minute shopping and baking to do -- who has time for a workout? With this routine, you do! This program packs a total-body strength and cardio routine in just seven minutes flat. Plus, it's quiet and works in small spaces (like your currently overcrowded house).
How it works: This efficient circuit keeps the heart rate up for both toning and a cardiovascular workout. The warm-up is built in to the total time of the program. Do as many reps as possible (AMRAP) with good form for 1 minute of each exercise, back to back, with little to no rest in between -- and then you're done!
